1. Presentation on The Quality Standards: ISO 9000,CMM,Six Sigma Presented By : Deep Dalsania (160350116002) Subject Name: Software Engineering Subject Code: 2160701 Submitted To: Prof. Deep Patel

2. Outline What is Quality Standards ISO 9000 Capability Maturity Model (CMM) Six Sigma

3. What is Quality Standards American National Standard Institute (ANSI) talks about standards as the base of a module on which the correctness or accuracy of others modules can be determined through thorough comparison and contrasting. Software engineering is a vast field, and the products created by software engineers must be of upmost quality. For this quality to be achieved, correct measures and grading standards must be followed, so as to achieve excellent products.

4. ISO 9000 It stands for International Organization for Standardization. ISO 9000 was created to produce an international set of process quality standards. First published in 1987 These are standards for quality management and quality assurance for any business. It applies     to process of creating, and controlling of products and services an organization provides, by giving an organized course for activities to be carried out to ensure that customer’s requirements are made

5. Who uses ISO 9000 Department of Food and Drug Administration, Energy, Defense, NASA, GSA Qualcomm, Cisco, IBM Adopted by the US as The American National Standards Institute (ANSI)/ASQC Q90 series US motor carrier industry Fed-Ex Banking, Healthcare, Manufacturing, Software, Service, etc.

6. Main Features of ISO 9000 Objective: "To promote the development of standardization and cooperation in the spheres of intellectual, scientific, technological and economic activities" ISO 9000 – concepts behind the management systems It is a set of standards for quality management and quality assurance ISO 9001 - Model for Quality Assurance in Design/Development, Production, Installation, and Servicing Generic Consistency between processes and results. Internal and external benefits

7. Main Features of ISO 9000 It is based on eight Quality Management Principles Customer-Focused Organization Leadership Involvement of people Process Approach System Approach Factual Approach Continual Improvement Mutually beneficial supplier relationship Customer satisfaction from design through service.

8. Capability Maturity Model (CMM) This model describes good practices for planning, engineering and managing software development . This practice allows software engineering organizations to create quality software while minimizing budget and time factors . CMM allows software engineers to judge and compare its processes to stated practices in the industry.

9. What is CMM? Capability Maturity Model is used as a benchmark to measure the maturity of an organization's software process. CMM was developed at the Software engineering institute in the late 80's. It was developed as a result of a study financed by the U.S Air Force as a way to evaluate the work of subcontractors.

10. What is Capability Maturity Model (CMM) Levels?

11. Level 1  (Initial): Where requirements for the system are usually uncertain, misunderstood and uncontrolled. The process is usually chaotic. Level 2  (Managed): Estimate project cost, schedule, and functionality. Software standards are defined Level 3  (Defined): Makes sure that product meets the requirements and intended use Level 4  (Quantitatively Managed): Manages the project's processes and sub-processes statistically Level 5  (Maturity): Identify and deploy new tools and process improvements to meet needs and business objectives

12. How long does it Take to Implement CMM? Typical times for implementation is 3-6 months  ->  for preparation 6-12 months  ->  for implementation 3 months  ->  for assessment preparation 12 months  -> for each new level

13. Limitations of CMM Models CMM determines what a process should address instead of how it should be implemented It does not explain every possibility of software process improvement It concentrates on software issues but does not consider strategic business planning, adopting technologies, establishing product line and managing human resources It does not tell on what kind of business an organization should be in CMM will not be useful in the project having a crisis right now

14. Six Sigma According to David Card, (IEEE Software 2000), Six sigma is “ A generic quantitative approach to improvement that applies to any process .” “Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects (driving towards six standard deviations between the mean and the nearest specification limit ) in any process -- from manufacturing to transactional and from product to service.” Six Sigma is a highly disciplined process that helps us focus on developing and delivering near-perfect products and services.

15. Key Concepts of Six Sigma Critical to Quality  − Attributes most important to the customer. Defect  − Failing to deliver what the customer wants. Process Capability  − What your process can deliver. Variation  − What the customer sees and feels. Stable Operations  − Ensuring consistent, predictable processes to improve what the customer sees and feels. Design for Six Sigma  − Designing to meet customer needs and process capability.

16. Myths about Six Sigma Six Sigma is only concerned with reducing defects. Six Sigma is a process for production or engineering. Six Sigma cannot be applied to engineering activities. Six Sigma uses difficult-to-understand statistics. Six Sigma is just training.

17. Six Sigma Methodology DMAIC Methodology DMADV or DFSS Methodology

18. DMAIC Methodology D efine -->  M easure -->  A nalyze -->  I mprove --> C ontrol Define  − Define the problem or project goal that needs to be addressed. Measure  − Measure the problem and process from which it was produced. Analyze  − Analyze data and process to determine root causes of defects and opportunities. Improve  − Improve the process by finding solutions to fix, diminish, and prevent future problems. Control  − Implement, control, and sustain the improvements solutions to keep the process on the new course.

19. DMADV or DFSS Methodology D efine -->  M easure -->  A nalyze -->  D esign --> V erify Define  − Define the Problem or Project Goal that needs to be addressed. Measure  − Measure and determine customers needs and specifications. Analyze  − Analyze the process to meet the customer needs. Design  − Design a process that will meet customers needs. Verify  − Verify the design performance and ability to meet customer needs.

20. Benefits of Six Sigma Generates sustained success Sets a performance goal for everyone Enhances value to customers Accelerates the rate of improvement Promotes learning and cross-pollination (is to bring these people together their knowledge and skills to influence each other). Executes strategic change Example: Mumbai Dabbawala
